Customers that think of Walmart as the place to get toiletries, groceries and more can now add cloud to the list.

Perhaps taking a page out of Amazon’s success with AWS, the retail giant has announced it is releasing its internally-developed cloud and application lifecycle management platform, called OneOps, open source to the public.

The service, which has seen two years of development by Walmart Labs, was used within the company and is designed to help develop and launch products more quickly, and maintain them.

One selling point that Walmart wants to drive home is that it is open and able to make use of various hybrid multi-cloud environments, preventing a “lock-in.”

Currently it is compatible with Microsoft Azure, Rackspace, CenturyLink Cloud, and “any cloud with an OpenStack endpoint.”

“By making OneOps available to the open source community, we’re enabling any organization to achieve the same cloud portability and developer benefits that Walmart has enjoyed,” Jeremy King, head of Walmart Labs and Tim Kimmet, vice president of platform and systems at Walmart Labs co-wrote in a joint statement.

Other features of OneOps include automated application management, portability which allows customers to move apps, databases or even environments between cloud providers, quick virtualization for development, and greater controls over tools and technologies.

One other differentiation is that Walmart is framing itself as a user, not a provider. With the release, it has provided all the code for OneOps on Github, and it has invited the public to improve on what is there.

“We’ve been an active contributor, releasing technologies such as Mupd8 and hapi with the community,” King and Kimmet said. “We’ve loved using and contributing to other popular open source projects like React, Node.js and Openstack. We welcome all comments and feedback from the community.”

OneOps, which was founded in 2011, was acquired by Walmart in 2013. TechCrunch reports that e-commerce sites including Walmart.com and Sam’s Club are built on the platform.

The retailer last made headlines last after announcing it would close 269 stores across, mostly in the US in an effort to refine its approach.
